What factor causes unpredictable daily effects when switching between different ginseng products?

Variability in product concentration and different processing methods leading to different ginsenoside levels.

Achieving consistent results from daily ginseng intake is often challenging due to extreme variability in product quality between manufacturers. Ginseng roots undergo different processing techniques, such as steaming for red ginseng or simple drying for white ginseng, which impacts their final composition. Furthermore, the concentration of the key active ingredients, the ginsenosides, varies widely based on factors like harvesting age and processing. This means that two capsules labeled identically by weight, such as 500mg from two different brands, may deliver vastly different actual doses of active compounds, leading to unpredictable outcomes like the unexpected onset of insomnia or blood pressure changes upon switching brands.
